ETM DIN Standard Long Life Bellows Sealed Stop Valves are zero emission and maintenance free. An uninterrupted metallic barrier is positioned between the piping and the environment. The components that during valve operation are subject to relative movements are welded onto the extremities of a metallic bellows that absorbs and compensates the shifting. Hence these valves are suitable for any fluid and are recommended when zero emission characteristics are required to protect the environment and the health of the workers from pollutive leaks, to prevent expensive wastes due to loss of energy and fluid, and to eliminate the not negligible cost of replacement of the packing. In conclusion, the valves are particularly suitable for dangerous, inflammable,lethal and explosive media.
